Well, based on the title "Endgame Principles" I immediately played 1.Bxh5 when after 1...gxh5 2.Kxf5 h4 3.Kg4 Black's kingside pawns fall and then it is a simple march with the king back to the Queenside.  To me that is a position-based "principle".

The actual solution - elegant as it is - seems more of a trick than a principle.

very easy.

So the King doesn't always need his IceQueen to do his dirty work...sometimes he takes out the garbage himself with some help from his little friend.

Pretty easy.
